Troubleshooting
This LCD monitor comes pre-adjusted with standard VGA
timing. Due to output timing differences among various VGA
cards, you may initially experience an unstable or unclear
display when a new display mode or new VGA card is selected.
Before applying any of the following troubleshooting
procedures, you should first apply the Auto Adjust option in the
OSD menu.
PROBLEM: Display is unclear and unstable
To stabilize and clarify your display, press the OSD menu
button, and adjust the clock and phase to obtain a clear display.
PROBLEM: There is no LCD display
If there is no display on the LCD, refer to the following:
1. Make sure that the power indicator on the LCD monitor is lit,
that all connections are secure, and that the system is
running on the correct timing. Refer to “Supported Timing”
on page 10.
2. Turn off the LCD monitor and then turn it back on again.
Press the OSD Menu button once and then press one of the
Adjustment Control buttons several times. If there is still no
display, press the other Adjustment Control button several
times.
3. If step 2 does not work, connect your PC system to another
external CRT. If your PC system functions properly with a
CRT monitor but it does not function with the LCD monitor,
and the LCD monitor’s power LED is blinking, the output
timing of the PC’s VGA card may be out of the LCD’s
synchronous range. Change to one of the alternate modes
listed in the “Supported Timing” section on page 10, or
replace the VGA card and repeat steps 1 and 2.
4. If the power LED is not lit, check that the AC power connector
is securely connected, and verify that the AC adapter LED is
lit. If the AC adapter LED is not lit, please contact your
dealer for assistance.
